What is machine base grouting?

Grout is poured between the two plate surfaces (normally steel and concrete) components to provide greater stability, alignment, vibration isolation, and leveling. Base plate grouting operations traditionally utilize cement grout.

How do you install grout under base plate?

grouting underneath steelwork and steel baseplates

  1. Step 0 – Shims used to temporarily level baseplate & steelwork.
  2. Step 1 – create a formwork around the baseplate.
  3. step 2 – use a hopper and pour in the grout.
  4. Step 3 – Wait for non-shrink grout to go off then remove formwork.
  5. step 4 – chamfer off corners on exposed edges.

What is the meaning of grouting in construction?

Grouting in civil engineering refers to the injection of pumpable materials into a soil or rock formation to change its physical characteristics. It is one of the ways ground water can be controlled during civil engineering works.

Why do you grout pump bases?

In addition to strength and stiffness, grouting locks the pump base to the foundation, making it heavier. This helps maintain the shaft-to-shaft alignment, reducing wear on the moving parts. Proper alignment minimizes wear on parts, which helps reduce the repair cost down the road for the end user.

How thick can you grout?

There is no standard for grout joints. According to the TCNA, the grout width can vary depending upon the size of the tile. Many stone and tile manufacturers suggest that grout joints be no less than 1/8″ to 3/16″.

What is the maximum grout thickness under base plate?

Thickness of Grout The thickness of the grout layer that is used in the constructions depends on the gap between base plate and footing and commonly is not less than 25mm. Also, ACI 351.1R-99 recommends the minimum mentioned thickness for hydraulic cement grouts in similar values.

What is the difference between epoxy grout and regular grout?

Unlike cement grout which is made from a cementitious powder mix , epoxy grout is made from epoxy resins and a filler powder. Epoxy grout is extremely durable and almost completely stain proof. Regular cement grout is not waterproof, so unlike epoxy grout , it can absorb water when wet and stain easily.

Which chemical is used in grouting?

Chemical Grouting is a form of permeation grouting. Solution grouts that are commonly used include acrylamides, polyurethanes, acrylates, epoxies and sodium silicates. There are two major types of chemical grouting: structural and water control.
